Life of Pi
How did they get a tiger on a boat in the middle of the ocean, you wonder? Well, they didn’t, but they did a pretty good job designing it. The tiger looks like a real-life Bengal-tiger, thanks to the advanced computer-generated animation.
They filmed a major part of the movie inside a huge tank, later adding the animation of the ocean and the tiger. AS you can see, the animator spent a year perfecting his animations in order to produce the perfect tiger.
